OK so they may only partially support it, or support it very badly. All the same if we can get m$ to start supporting open formats surely that is a step in the right direction? No doubt they will try and add something in there that makes it different to the open document format but if they can be influenced to support it then it shows even M$ is trying to adopt elements of opensource and all their expensive advertising into the dangers and costs of open source will be wasted. M$ could cause themselves to lose quite a lot of money in counterproductive advertising, surely that is a good thing for everyone else?
